Patented Mar. .10, 1931 OTTO LESTER INGWERSEN, F WAYNE, NEBRASKA WINDOW VENTILATOR Application filed October 7, 1929. Serial No. 398,054.

The present invention relates to ventilators, and has for an object the construction of a ventilator which may be incorporated in the construction of'a storm sash whereby the interior of a house may .be

ventilated from time to time without removing the storm sash.

Another object of the present invention is to provide a construction of ventilator which may be incorporated in a storm sash without materially altering the structure of the storm sash, and wherein the ventilator does not add to any appreciable extent to the thickness of the storm sash, nor does it change the appearance of the storm sash to any appreciable extent.

Another object of this invention is to provide a ventilator of this character which may be incorporated in a storm sash having a number of panes, and wherein the ventilator may be mounted in the storm sash either at one side or centrally thereof, and wherein the ventilator is easy of access so that it may be adjusted to different heights so as to ventilate the enclosure as desired.

The invention also aims to provide a ventilator structure for application to a storm sash or the like wherein the center rails of the sash are not disturbed, and wherein the ventilator structure embodies certain fillerin stop strips adapted to fit into the rabbets and other parts of the storm sash for supplying supplementary stop strips to support the ventilator sash.

The above, and various other objects and advantages of this invention will in part be described in, and in part be understoodfrom, the following detailed description of the present preferred embodiments, the same being illustrated in the accompanying drawing, wherein:

Referring now to the drawings,

and first to the construction shown in Figure 1, l0 and 11 designate the side rails, and 12 and 13 designate the top and bottom rails forming the frame usual construction.

of a storm window or sash of The frame 1s provided with horizontal sash bars 1% and one or more vertical sash bars 15, depending upon the number of panes 16 of glass with which the storm window is provided.

The ventilator of this invention comprises a small sliding frame 17 of substantially the dimensions of one of the panes 16, and is adapted to take the place of one of the panes 16, as shown in the drawings.

The frame 17 carries therein a pane of glass 18 which may be one of the panes l6 cut down to fit in the sliding frame 17.

The frame 17 is of a width slightly less than the width of the opening between the vertical side rail 11 and sash bar 15 as shown in Figure 1, or between the sash bars 15 in Figure 2 of the storm sash in which the ventilator is fitted. A supplemental parting stri of the 19 is fitted along each lateral edge rame 17 and is shaped to the configuration of the adjacent vertical sash bar 15 and sash rail 11 and is provided with the usual overhanging flange, for engaigin the outer face of the sliding frame 17 or molding the same in the storm sash. The vertical sash bar 15 is of the usual construction and provided with a stop shoulder 20 against which the pane 16 is usually seated, and which in the present instance provides a support for an. outer stop strip 21 which is secured to the vertical sash bar 15 or the like, as shown in Figure 7, and which overlaps the' outer side of the ventilator frame 17 v The stop strips 19 and 21 therefor provide a guide or runway for holding the ventilator frame 17 in the plane of the storm window. It will be noted from Figure 10 that the outside stop strips 21 terminate at their upper ends against the lower edge of the upper pane 16 so as to support the pane 16 in the upper portion of the window and to also provide means for holding the outer side of the ventilator frame 17 flush with the inner side of the pane 16. The pane 16 provides a stop strip or support for the ventilator window 17 when the latter is raised above the ventilating opening through the storm sash. By use of these inner and outer stop strips 19 and 21, it is unnecessary to change the configuration or construction of the storm window and the device is practically an attachment which may be applied by inerely removing one of the panes 16. The inner stop strip 19 may be provided upon its top portion, as shown in Figure 5, with a lower keeper notch 22 adapted to receive the outer end of a spring bolt 23 secured upon the upper edge portion of the ventilator sash 17 for locking the ventilator sash in lowered position. As shown in Figure 6, the inner stop strip 19 may also be provided with a second keeper notch 24 for locking the ventilator sash 17 in raised position.- The inner stop 19 at the opposite side of the ventilator sash 17 of the same construction as shown in Figure 7 and is of suflicient depth to receive a tension spring 25 which is secured to the adjacent side of the sliding frame 17 and adapted to hold the same frictionally in adjusted position and also against rattling or vibrating incident to wind pressure.

It is apparent that the ventilating frame maybe mounted in the storm sash at any suitable point provided there is a flat pane of glass 16 above the ventilating opening which admits of the upward sliding adjustment of the ventilator frame 17. In Figures 2 and 4 there is shown a slight modification in the location 'of the ventilator, these figures showing the ventilator mounted at the central portion of a storm sash which is wider than the storm sash shown in Figure 1. In Figure 2 the storm sash is provided with two vertical sash bars 15 between which the ventilator frame 17 is mounted, and in this instance the inside stop strips 26 may be in the form of flat strips of wood or the like which are secured by nails, or otherwise, to the inner sides of the vertical sash bars 15, as shown in Figure 4. Otherwise, the construction of the parts is identical with that shown in Figures 1 and 3. The stop strip features of the invention is to adapt the inner stop strip to the configuration of the side or central vertical rails or barsof the storm sash so as to provide suitable guide ways and auxiliary stops for the sliding ventilator sash 17 whether it is mounted at one side or at the central portion of the storm window.

In use, it is only necessary to retract the bolt 23 and move the sash 17 upwardly to the desired extent when the frictional contact of the spring 25 and the bolt 23 will hold the sash 17 at the desired heighth. The keeper notches 22 and 24 are adapted to serve as means for positively locking the ventilator sash 17 in either raised or lowered position. It is therefore only necessary to raise the ventilator sash 17 after the inside windows have been opened so as to ventilate the room or interior of obviate the necessity of removing or hingedly or otherwise mounting the storm window.

The bottom rail 13 of the storm sash may have a beveled mortice 27 therein at the upper edge and at its inner side to accommodate the fingers in catching the bottom of the ventilator frame 17 to raise it.

It is of course understood that various changes and modifications may be made in the details of construction and design of the several parts which comprise the improved ventilator without departing from the spirit of this invention, the changes and modifications being restricted only by the scope of the following claims.
